I spend some time reading well researched and founded studies that break down verifiable data using methodology that is reasonably comprehensible. Occasionally I run across a subject that will have 'dueling' studies involving roughly the same data sets. Such studies provide the research basis for articles such as this WaPo piece which is supported by this this NPP study. NPP is the National Priorities Project which can be found in alliance with the Soros Foundation and the Tides Foundation on most subjects.
